It is also capable of detecting, amplifying and controlling certain energies, sound, signals, frequencies, and waves, allowing the Doctor to intercept a teleporting individual and send them where he chooses, scan and identify matter, send out communications, enhance sounds, signals, and frequencies, and acting as a catalyst or conduit for energies.
The War Doctor also used his sonic in tandem with the Tenth and Eleventh's to create a force field wave to repel a Dalek.
[3] During the Third Doctor's tenure, producer Barry Letts was adamant that the device should not become a cure-all for the series and limited its use to avoid writers becoming over-reliant on it.
In The Sea Devils, the Doctor used it to detonate landmines; Michael E. Briant explains that this was feasible, stating that the sonic waves shook the mines.
In the DVD commentary, Letts himself remarks on the thickness of the prop and the fact that it belies the idea that it was the regular one, prompting Katy Manning to question whether it was indeed a sonic screwdriver.
[4] This was due to the serial being produced out of transmission order: the original sonic screwdriver prop went missing during the recording of Carnival of Monsters (1973), requiring a new prop to be built for the rest of the season;[5] The Three Doctors was recorded after Carnival, but set before it, so the screwdriver could be seen to revert to its previous appearance for one story after The Three Doctors before receiving a more permanent redesign thereafter.
Exceptions include Robot (which was the last story to be produced by Barry Letts), where it was again used to detonate mines, and as a "miniature sonic lance"[note 1] to cut out a lock.
It is depicted as being smaller and sleeker than the Doctor's, and he was sufficiently impressed with her design that he attempted to swap screwdrivers with her in The Horns of Nimon (1979–80).
Over the course of the next two years, the props were continually repaired and modified, with some additions being a new thumb slider design and different colours of wires used in the clear channel when extended.
Some of the uses in the new series include: repairing electronic equipment; re-attaching materials such as barbed wire; detecting, intercepting and sending signals; remotely operating the TARDIS; burning, cutting, or igniting substances; fusing metal; scanning and identifying substances; amplifying or augmenting sound; modifying mobile phones to enable "universal roaming"; disabling alien disguises; resonating concrete; reversing teleportation of another entity.
In "Closing Time" (2011), ringed energy beams are seen emitted from the device, giving it a more weapon-like appearance, particularly when used to disable a weakened Cyberman at a distance.
In "Smith and Jones", the sonic screwdriver burns out after the Doctor uses it to amplify the radiation output of a hospital X-ray machine.
The Eleventh Doctor's sonic screwdriver is larger than its predecessor; it has a green light and metal claws that extend with a flick of the wrist.
In "A Christmas Carol" (2010), the Doctor advises a young Kazran Sardick to pursue romance while implying that in a similar situation in his own past he had instead gone to his room to "design a new kind of screwdriver."
In "Let's Kill Hitler" (2011), it is explained that instead of having settings, this version operates through a psychic interface, basically doing whatever the user thinks of while pointing and holding down the button.
This version of the screwdriver also appears, although never officially announced, to have a flashlight setting, as the Doctor is seen to have it emitting a continuous glow while not uttering the classic sonic noise.
It is similar to a Tuxedo cane, except the top replaced with the upper portion of his screwdriver, with a metal ball cut in fourths attached to the claws.
The Doctor uses his telescopic screwdriver previously seen in the TV movie, rather than his updated steampunk version which had been used in numerous Big Finish audio dramas.
In addition, when combined, the screwdrivers of the War, Tenth, and Eleventh Doctor could create a sonic force field blast to repel and destroy a Dalek.
"The Magician's Apprentice" (2015) shows that the sonic screwdriver can create "an acoustic corridor" so that the Twelfth Doctor can communicate with a boy trapped in an extraterrestrial mine field.
The new screwdriver has seen use in the spin-off show Class, where the Doctor increases the voltage of flood lights to expel the Shadow Kin and partially close a rift in space-time.
In "The Woman Who Fell to Earth", the Thirteenth Doctor is depicted constructing a new sonic screwdriver out of scrap metal and an orange glowing device from an alien travel capsule.
[11] In the first of the specials "The Star Beast", this screwdriver is shown to have upgraded functionality, such as being able to draw out maps and graphs, and also being able to create energy shields to block a corridor.
Michael van Kesteren, prop art director, said that he struggled to come up with a concept; adding that the team had been "quietly hoping not to have to do another one for a while", as the creation of the previous sonic was "such a complicated, time-consuming process".
[18] Jason Davies-Redgrave, art department co-ordinator, wanted to think "as far out of the box" as he could, and sketched ideas based on a flip phone, a pebble, and an "alien croissant".
The sketches were divisive at first, with Joel Collins, executive producer, elaborating that "if you'd got out of bed on the wrong side, you might have looked at what Jason had drawn, gone 'what is that?
A metal version of the sonic screwdriver produced by Wow Stuff mounts a functional set of changeable flat and Phillips heads under a removable cover as well as providing light and sound effects.
[24][better source needed] QMx later released an Artisan Master Series replica of River Song's sonic screwdriver, limited to a run of 15, also made by original prop maker Nick Robatto, which has also sold out.
[25][better source needed] The Wand Company released a universal remote control styled on the Eleventh Doctor's sonic screwdriver on 3 August 2012.
[32][better source needed] Character Options have also released toy versions of the Third, Fourth, Fifth, and Eighth Doctors' Sonic Screwdrivers.
